Streptococcus bovis HC5 produces a broad spectrum lantibiotic (bovicin HC5), but S. bovis JB1 does not have antimicrobial activity. Preliminary experiments revealed an anomaly. When S. bovis JB1 cells were washed in stationary phase S. bovis HC5 cell-free culture supernatant, the S. bovis JB1 cells were subsequently able to inhibit hyper-ammonia producing ruminal bacteria (Clostridium stickland...

Studies that detected an association between Streptococcus bovis endocarditis and colon carcinoma have not taken into account the recently identified genetic diversity among organisms historically classified as S. bovis. With near full-length 16S ribosomal DNA sequence analysis, organisms cultured from the blood of endocarditis patients at the Mayo Clinic from 1975 to 1985 and previously identi...

Streptococcus bovis (S. bovis) bacteria are associated with colorectal cancer and adenoma. S. bovis is currently named S. gallolyticus. 25 to 80% of patients with S. bovis/gallolyticus bacteremia have concomitant colorectal tumors. Colonic neoplasia may arise years after the presentation of bacteremia or infectious endocarditis of S. bovis/gallolyticus. The presence of S. bovis/gallolyticus bac...

Immunodiagnostic methods based on the detection of antibodies continue to be the most effective and practical methods for the diagnosis of imported schistosomiasis. Schistosoma bovis is a species whose final natural hosts are bovines, ovines, caprines, and small wild ruminants. Different studies have demonstrated the analogies existing between S. bovis and other Schistosoma species which affect...

BACKGROUND Streptococcus bovis has long been associated with colorectal cancer (CRC). However, not all genospecies are as closely related to CRC. With this systematic review, we aim to increase the awareness of the association between S. bovis biotype I (Streptococcus gallolyticus) and CRC and urge for uniform molecular microbiological classification. METHODS In January 2011, the PubMed datab...

in a series of heterologous immunity studies s. haematobium, s. bovis and o. turkestanicum in calves, a large number of s. haematobium cercariae (21,000 cercariae) were used repeatedly as the immunization agent. at autopsy, 22 weeks after initial exposure, immature s. haematobium was detected. thirteen weeks after initial exposure a group of calves was challenged with s. bovis and another group...

Streptococci identified as Streptococcus bovis, S. bovis variant, and Streptococcus salivarius were examined with respect to physiological and serological characteristics and cellular fatty acid content. Similarities in physiological reactions and problems encountered in serological analysis were noted, suggesting that an expanded battery of physiological tests is needed to definitively identif...

We characterized 22 human clinical strains of Streptococcus bovis by genotypic (16S rRNA gene sequence analysis [MicroSeq]; Applied Biosystems, Foster City, Calif.) and phenotypic (API 20 Strep and Rapid ID32 Strep systems (bioMerieux Vitek, Hazelton, Mo.) methods. The strains, isolated from blood, cerebrospinal fluid (CSF), and urine, formed two distinct 16S ribosomal DNA sequence clusters. Th...

Streptococcus bovis has been identified as a causative agent in humans for a variety of diseases, including endocarditis, meningitis, and septicemia. Identification of S. bovis strains of human origin in clinical settings has been problematic due to variations in biochemical tests as compared to ruminal strains of S. bovis, and other streptococcal species. DNA-DNA hybridization with chromosomal...
